THlLL-EQUALIZER FOR ROAD-CARTS.

SPECIFICATION forming part of Letters Patent No. 358,876, dated March 8,1887.

Application filed December 16, 1886. Serial No. 221,709. (No model.)

To all whom it may concern.-

Be it known that I, JAMES PERcY,'a citizen of the United States, and aresident of Chicago, county of Cook, and State of Illinois, haveinvented new and useful Improvements in Thin-Equalizers for Road-Garts,of which the following is a specification, reference being had to theaccompanying drawings, illustrating the invention, in which- Figure I isa side elevation of one thill combined with my attachment; Fig. II, acentral vertical section of Fig. I, between the dotted lines :0 m,- Fig.III, a top or plan view of Fig. I; Fig. IV, an enlarged broken view ofFig. I, with the thill-spring down, as when the weight of a person isthrown on the thills in getting in or out of the cart; Fig. V, aperspective representation of the inner end of the forward portion ofthe two-part thill; Fig. VI, a trans verse section of Fig. IV, taken online 2 z, looking in the direction indicated by dart f.

The purpose of this invention is to provide simple and more. effectivemeans for equalizing the horse motion of road-carts and like two-wheeledvehicles.

In carrying my invention into practice I construct the thills in twoparts each, as has been before done, but employ wholly different meansto break the horse motion between the thill-straps and the body of thecart.

Instead of forming the butt-joints separating the two-part thills atright angles with their bottom faces, the joints in my device are formedon such an angle, as shown at J, that the forward parts,A,of the thillsare prevented from passing below the T-iron F by lapping onto thebeveled ends of the back portions, B, of the thills. The T-irons F,which are now 1 employed on the ordinary singlepiece thills,

are made to stop at the inner ends of the back portions, B, and to forma portion of the laps for the beveled ends of the forward portions, A,to bear against when the parts are in position as shown at Fig. IV.

The springs which connect the parts A B are shown in Figs. I, II, IV,and VI at E II, the part E, back of the joint J, being secured to theparts B by the same bolts, a, which sccure the T-irons F, and by clips GG, of ordinary construction, and the forward portions of the springs arebolted to the parts A at a n.

The forward portions, A, are formed of a depth less than the parts B,that their inner ends may have the required lateral movement between thespring E H and stopplate D to break the horse motion given to the thillsat their joint-connections, so that the body of the cart will move alonglevel notwithstanding the forward ends of the thills have verticalreciprocating movements. At Fig. IV the thill is shown depressed, aswhen the weight of a person is thrown thereon entering the body of thecart, and as when the end of the thill has the highest position by thehorse motion. The dotted lines 20 show the position of the forward part,A, when its forward end has the lower position by the horse motion. Astop, (2 m, is secured to the top portion of the inner end of the partA, and aslot is formed in the forward end of the plate D to engage it,whereby the part A is controlled in the downward horse motion to theposition shown by said dotted lines w.

From the foregoing it will be seen that the inner end of the part A hasa free movement between the plate D and the draft-spring H E. To preventany noise of these parts, the inner end of the part A may be providedwith a rubber band, 0, Fig. V. The clip 0 G not only holds thedraft-spring H E and slotted plate D in place, but it serves to concealthe jointconnection and gives a neater appearance to the device.

Itis not new to equalize the horse motion of two-wheeled vehicles, asthis has been done by various mechanisms different from those hereindescribed. I therefore confine my invention to the claim presented.

I claim as new and desire to secure by Letters Patent of the UnitedStates In mechanism for equalizing the horse motion of two-wheeledvehicles, the two-part thills A B, with overtopping joints J, and thepart A, formed of less depth than the part B, and provided with the stop(I m, in combination with the slotted plate D, engaging the said stop,the draft-spring H E, and the clip 0 G, as specified.
